So driving the other day and tow haul starts flashing. I come to a stop sign and goto take off and it barley takes off. It will barley roll if my foot is off the pedal sometimes wont even roll. Also won't shift into 6th. Once it gets rolling though say till about 25 it's fine. Just doesn't wanna take off? I scanned the trans but got no codes. And here are some pressures and stuff but I don't know what I'm looking for with the trans. This was all done in park.
The only thing I can think of would be TPS ( throttle position), and EGR duty , if it lags dead petal, hopefully Mark K will chime in you have the thread posted right to catch his eye, in the mean time run the EGR tests and post , remember to get them like this if possible
In park
Post Koeo( key on engine off
Low ,just idle no radio , lights , HVAC off
High , 2500 rpm steady
Get each one at the ford specs
Yes sir add into your gauge TPS Throttle position sensor , you will have one at the EGR too but the one under the petal , seeing that your EGR is deleted .
Well hopefully its the solenoid as mine was doing the same thing with the t/h light flashing. I got a code saying solenoid c stuck or off and replaced it.. still didnt work. Dealer says clutch pack. Hope yours is the solenoid. My tranny is still being built.. and its a painful wait.
Well I sure hope I don't have to rebuild it. But I guess I was planning on doing it this winter anyways. But I wanna finish riding it out till then hahah
If it turns out to be a toad you may want to just replace it.
I got a very good deal when mine puked on me.
Take to Ed over at FICMrepair if you need a trans. He can do
wonders on the price for a real Ford trans.
, in the mean time run the EGR tests and post , remember to get them like this if possible 
glad I re scanned the thing just saved a ton of money
